Fix a bunch of dataset names
Created by: scarlehoff
The process for a few datasets is wrong:
CMS_Z0_8TEV_PT-Y: CMS_Z0J_8TEV_PT-Y
ATLAS_WMWP_13TEV_TOT: ATLAS_WPWM_13TEV_TOT
CMS_WP_7TEV_ELECTRON_ASY: CMS_WPWM_7TEV_ELECTRON_ASY
CMS_WP_7TEV_MUON_ASY: CMS_WPWM_7TEV_MUON_ASY
edit: regression tests will fail because the seed depends on the name
